Referring to the drawings in, detail, lill desigv nates, according to each form of the invention, the cylindrical outlet end portionof a supply conduit, for air to be usedv for heating, cooling on other punposes, designatesiaf disk-lilrewall emendingy across the end of said conduiaand; I2 designates,.generally, a cap membeneng-agediover said conduit end portion and rotatable with respect thereto.

In thef, side wall of the'co-nduita end portion' IlldsI arrV annular row of` openings# |31 and; intermediate ciosed portions III of approximately, equalwidths and lengths, while in the end wall II is another annular row of openings I5 and intermediate closed portions |6 which, likewise, are of approximately equal widths and lengths. Moreover, the openings I3 and the closed portions I4 are of approximately the same lengths, angularly, as the openings I5 and the closed portions I8.

The cap member I2 includes a cylindrical side 4 Glaims.. (CL, 98-40.)-

On the otherl hand, accordingV to. they Figs. 1, and 2: constnuction. theJ endg walls I l' and.

@briouslyg theain deflector zmay be'replacedf by` an: air deflector ofi any` otherl form. to causey ain discharged throught the; openings |31` and` |8 to have any desired; direction=of flow relativeto the conduit Il); Gbviously, too;v the` devicel may be devoid ot any:- air? delector fon controlling. the directionof\ flow of; ainy dischargedt throughf the openings I3 and I8, 'in which event the ilow from said openings will be laterally relative to the conduit I. Furthermore, air deflector means may be provided, if desired, to cause air discharged through the openings I5 and 2| to follow any desired direction of flow relative to the device.

According to the construction shown in Fig. 3,

the portion of the side wall I'I of the cap member I2 rearwardly of the openings I8 is turned outwardly and forwardly in overlying relationship to said openings I8 to provide an annular air deflector 24 which is effective to cause air discharged through the openings I3 and I8 to take a direction of ow outwardly and forwardly relative to the device. Alternatively, the air deflector 24 may be a part separate from the cap member I2. Also, according to the construction shown in Fig. 3, the end walls II and I9 are of rearwardly and inwardly inclined conical form and the edges of the openings I5 and 2| are at right angles to said walls so that air discharged through said openings is caused to have a direction of flow toward a prolongation of the axis of the conduit I0. If desired, this same effect may be attained in a construction as illustrated in Figs. 1 and 2 by inclning the side edges of the openings I5 and 2|.

The cap member I2 may be connected to the conduit end portion I8 in any suitable manner as, for example, by means of a rivet 25 or the like extending centrally through the end walls II and 20. Also, any suitable means may be provided for use in effecting rotation of the cap member I2. For example, said cap member may be provided with one or more hand or foot engageable arms 26 extending laterally therefrom as shown in Fig. 3.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.

We claim:

1. Air ow control means comprising an air supply conduit member including side and end walls each having therein an annular row of spaced apart openings for outlet of air therefrom, and a cap member rotatably mounted on said conduit member and including side and end walls each having therein an annular row of spaced apart openings for alinement with and disaline` ment from the openings of the corresponding row in the side and end walls of said conduit member, respectively, by rotation of said cap member relative to said conduit member, thereby to control discharge of air from said conduit member through the sets of openings in the side and end walls thereof, respectively, and air deflector means mounted on one of said members and disposed to intercept air discharged through the openings in the side walls of said conduit member and said cap member and to cause it to take a desired direction of flow relative to the direction of flow of air discharged through the openings in the end walls of said conduit and said cap members, said air deflector means extending around said cap member and being open at one end and closed at its other end and being secured at its closed end to the member on which it is mounted.

2. Air flow control means comprising an air supply conduit member including side and end walls each having therein an annular row of spaced apart openings for outlet of air therefrom, and a cap member rotatably mounted on said conduit member and including side and end walls each having therein an annular row of spaced apart openings for alinement with and disalinement from the openings of the corresponding row in the side and end Walls of said conduit member, respectively, by rotation of said cap member relative to said conduit member, thereby to control discharge of air from said conduit member through the sets of openings in the side and end walls thereof, respectively, and air deflector means carried by and extending from the side wall of said cap member into overlying relationship to the openings in said side wall to intercept air discharged through said side wall openings and to cause it to take a desired direction of flow relative to the direction of ow of air discharged through the openings in the end walls of said conduit and said cap members, said air deflector means extending around said cap member and being open at one end and closed at its other end and being secured at its closed end to said cap member.

3. Air flow control means comprising an air supply conduit including side and end walls each having therein an annular row of spaced apart openings for outlet of air therefrom, and a cap member rotatably mounted on said conduit and including side and end walls each having therein an annular row of spaced apart openings for alinement with and disalinement from the openings of the corresponding row in the side and end walls of said conduit, respectively, by rotation of said cap member relative to said conduit, thereby to control discharge of air from said conduit through the sets of openings in the side and end Walls thereof, respectively, the end walls of saidv conduit and said cap member being of rearwardly and inwardly inclined conical form and the inner and outer edges of the openings in said end walls being disposed perpendicularly to sai-d walls so that air discharged through the openings in said end walls is caused to flow toward a forward prolongation of the axis of the conduit.

4. Air flow control means as set forth in claim 1 in which the inner end portion of the cap member is extended outwardly and forwardly relative to said cap member to provide the air deflector FRIEDRICH HONERKAMP. FRANZ J. KURTH.
